An odd sort of symmetry about E=MC^2

  1. Mar 26, 2005 #1
    You sacrifice mass to create energy (energy is just mass with a velocity), and the faster mass moves (relativity) the more massive the mass gets, is there some sort of significance to that? I hate riddles.

    The question is unclear.

    E=MC^2. Destroy mass, create energy. -1 mass +1 energy.

    Lorenze Transformation equation. Faster you go (sacrificing energy, propulsion), the more massive mass gets. +1 mass -1 energy.

    An answer to you riddle.

    Energy is force x distance. A stationary mass has rest mass and therefore rest energy. This rest mass used energy to create it - in its structure, force moved through a distance and is stored as potential energy (PE).
    When this mass moves it gains kinetic energy (KE).

    Now the faster mass moves the more massive it seems to get. Well this is not an increase in physical mass, but is an effect brought about by the effects of force propagating at the speed of light. It's a bit like pushing a child on a swing. As the child moves faster, your hand has less push effect because it moves at the same speed as the swing. This doesn't mean the child's mass has increased, it only means that the effect of the push weakens.

    Also when particles change type, ie, big to small, the release of potential energy gives the smaller particle more speed (PE changes to KE).
